well the drum does not have a screw off top, it looks like you pop the seal in the center, then you can store it in another container, which is what I will have to do I guess...

I was hoping for a lip or top for the drum that would allow me to store it in the drum, but I guess not..

 

I think something along those lines will work, although it would have to be not vented and air tight so as to not pull in air resulting in water getting added...

 

The 55 gal drum has a screw-in bung under the seal. I'm not sure you can get it in the smaller drums that nitromethane come in.
if it is the smaller drum, looks like you can buy a cap for it:
